BQ24295 Smart Battery Charger IC with Boost + OTG

Last Updated on May 29, 2025 by Swagatam Leave a Comment

This BQ24295 IC is like a super smart charger chip. This one is not just for charging battery, but also doing many other jobs like boost converter, USB detection, power path control, and even OTG (host power supply). So we can say that this is a full battery charging and power management IC. Let us […]

INA219 Current Sensor Circuit Diagram and Datasheet

Last Updated on May 16, 2025 by Swagatam Leave a Comment

In this post we are going to understand this sensor called INA219, and this one is like a full smart sensor. It not only tells how much current is flowing but also tells voltage, and also calculates power, all in digital form. That means it talks with microcontroller through I2C lines. It is like an […]

IC LM7912, -12V Negative Voltage Regulator Explained

Last Updated on April 25, 2025 by Swagatam Leave a Comment

In this post we are going to learn about one super old but gold IC called LM7912 or simply IC 7912. This one is not positive regulator like 7805 or 7812, but it is negative regulator which means it gives -12V output and not +12V. If you are making op-amp circuits or dual power supply […]
